METHOD OF LASTING BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 371,713I dated October18, 1887. Application filed June 2, 1887. Serial No. 240,031. (Nomodel.)

.To all whom it may concern.:

Be it known that I, AARON F. SMITH, of Lynn, in the county of Essex andState of Massachusetts, have invented certain new and usefulImprovements in'Methods of Making Boots or Shoes, of which the followingis a specification.

This invention relates to the manufacture of boots or shoes of the kindshown in Letters Patent of the United States granted to A. Seaver, April5, 1887, No. 369,822; The shoe described in said patent has no innersole, and the only sole that is employed is secured to the upper,firstby cement while the upper is on the last, and then by stitches orother permanent fastenings after the upper is removed from the last. Theabsence of an inner sole gives the shoea very flexible bottom. It is notdesirable, however, that the shank portion of the sole be as flexible asthe fore part, particularly in high-heeled shoes, and it has been foundthat the shanks of such shoes, when made entirely without an inner sole,will not hold their shape as perfectly as is desirable. i

My invention consists in the improved method hereinafter described ofmaking boots or shoes, whereby the desired flexibility of the fore partandstiffness ofthe shank are secured.

Of the accompanying drawings, forming a part of thisspecilicatiom'Figure 1 represents a longitudinal section of the upperand inner sole on the last. Fig. Zrepresentsalongitudinal section of ashoe made by my improved method. Fig. 3 represents asection on line wx,Fig. 2, looking downwardly. Fig. 3u rep resents a similar sectionshowing the edge of the upper cut away over the exposed surface of thefore part.

The sameletters of reference indicate the same parts in all the figures.

In carrying out my invention I place on the bottom of the last b a halfinner sole, t, formed to cover thebottom of the heel and shank of thelast, and terminating at or near the ball, leaving the fore part of thelastfbottom uncovered. The forward end of the half inner sole is reducedto a thin or knife edge, as

shown. I then place the upper a on the last and draw its edges over thebottom of the half inner sole and over the uncovered fore part of thelast-bottom, using stitches o, Fig. 3, or any other suitable means tosecure said edges in place, so as to retain the upper on the lastwithout preventing the removal of the last from it. I then cement to theouter surfaces of the edges of the upper, which lie upon the bottom ofthe half inner sole and last, an outer sole, e, using in the cementingoperation a sole-laying machine having a molded yielding sole shapedpad, which presses the cement-coated outer sole against the edges oftheupper and molds or conforms the outer and inner soles to the shape ofthe bottom of the last, the molded sole and upper being held in shape bythe cement connection. When the cement has sufficiently set, I removethe shoe from the last and permanently unite the outer sole, upper, andhalf inner sole by stitches or other permanent fastenings, d.

I prefer to eut or trim away the edge of the upper that lies on the forepart of the inner sole, as shown in Fig. 3, 'said edge being cut away-close to the line of stitches, thus removing the greater part of theedge of the upper and all of the lastingstitches c lying on theuncovered fore part of the outer sole, so that a smooth surfaceisafforded,which will greatly enhance the comfort of the shoe. Theoperation of cutting out the edge of the upper will be performed afterthe permanent connection of the outer sole to the upper, and by asuitable cutting device inserted in the shoe for that purpose. It willbe seen that the shoe thus made combines the flexible fore part of theSeaver shoe above referred to with the stier shank of the ordinary shoehaving a full inner sole.

I claim l. The improved method' of making unturned boots or shoes havingan inner sole which extends from the heel along the shank and terminatesat or near the ball, which consists in lasting the upper to the innersole, the edge of the upper being turned over upon the bottom of saidinner sole and upon 'the loottom of the fore part of the last,oernenting the outer sole to the inwardly-turned edge of the upper, and.then permanently uniting the outer sole to the inner sole and upper7 asset forth.

2. The improved method of making looots orA shoes, having an inner solewhich extends from the heel along the shank and terminates at or nearthe ball, which consists in lasting the upper tothe inner sole, the edgeof the upper being turned over upon the bottom of said inner sole andupon the bottom of the fore part of the last, cenienting the outer soleto the inwardlyturned edge of the upper, then permanently uniting theupper, inner sole, and outer sole, and nally cutting out the edges ofthe upper along the uncovered fore part of the outer` sole, as setforth.

In testimony whereof l have signed my name to this specification, in thepresence of two subscribing witnesses, this 26thV day of May, A. D.12587. l
